This invention concerns a package with safety lid and seal.
Various systems are already known for closing cans and bottles with safety lids and stoppers. Some of them are provided with a seal and many of such packages are devised for containing toxic products which might be detriment to health and that therefore should be kept out of the way of children before opening or emptying the packages.
From among these known packages, there are those comprising a body basically cylindrical with a lid coupled by means of a thread at the mouth thereof and which comprises an outside coaxial skirt showing on its inside face projections that meet other projections of the body of the package in order to stand in the way of opening.
It is precisely such kind of packages that become improved as a result of the present invention, particularly characterized by the fact that the lid offers safety with the seal attached and also after it is removed.
For this purpose it is characteristic in the present invention to have around the body of the package a seal made up of a strap or ring weakly joined to the body and showing on the periphery at least one recess into which will fit the corresponding projection of the skirt of the lid, thus standing in the way of the unscrewing. One of the ends of the sealing strap includes a handlelike extension facilitating through pulling, the tearing off and separation of the sealing strap with respect to the body of the package.
It is also characteristic of the present invention that the body of the package has on its periphery an elastic projection incorporating a tooth as a safety means against unscrewing of the lid after the seal is removed. The tooth stands in the way of the projections in the skirt of the lid as the latter is being unscrewed, and that the tooth is avoided when the elastic projection is pressed down.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which preferred embodiments of the invention are illustrated.
FIG. 1 is a perspective view of the top of the body of the package and the lid, uncoupled,
FIG. 2 is a partial cut view of an elevation of the package, complete and closed,
FIGS. 3 and 4 correspond to a cross section view of the package along line III--III of FIG. 2 with and without a seal respectively, and
FIG. 5 is a detailed cut elevation of the safety means which operate after the seal is removed.
According to the drawings, the package comprises a body essentially cylindrical 1 and a circular lid 2. The lid shows an inside thread 3 and an outside coaxial skirt 4 which in two diametrically opposed spots has inside corresponding lid projections 5 and 6.
Around the body 1 of the package is formed a seal made up a of strap or ring 7 weakly joined through an edge or attachment means 8 to the body. On the strap 7, two recesses 9 and 10 have been incorporated and are diametrically opposed on its periphery. The two recesses 9 and 10 recieve projections 5 and 6 respectively of the skirt of the lid. This prevents the unscrewing of the lid after the lid has been coupled through axial pressure to the mouth of the body 1 of the package avoiding the outside thread 11 of the periphery thereof thanks to the semi-resiliency of the material of which body and lid were manufactured, to the slight gap there is between the threads of either, and to the slant planes comprising them.
One of the ends of the sealing strap or ring 7 is already separated from the body 1 along a short length 12. The short length of 12 comprises an expansion or extension 13 with a rim 14 that facilitates in a handlelike way, by pulling as shown by arrow F, the tearing off and separation of the sealing strap 7 with regard to the body of the package. The short length 12 and the expansion 13 being removal means.
Sealing strap 7 leaves free a small area of the periphery of body 1, where the body has a body projection 15 forming a resilient bridge bearing a tooth 16 aligned with the sealing strap 7 to serve as the safety medium against unscrewing of the lid after the sealing strap has been removed, since the tooth 16 collides with the projections 5 and 6 of the skirt of the lid when the latter turns (FIG. 4). To unscrew the lid, the obstacle of tooth 16 can be avoided by pressing projection 15 in a direction as shown by arrow F' in FIG. 5, whereby the projection bends towards the body 1, thus tooth 16 ceases to prevent the passage of projections 5 and 6 of the skirt of the lid.
To facilitate screwing the lid on the body of the package, the projections 5 and 6 of the skirt of the lid and the tooth 16 present slanted planes 17 and 18, and opposite to such slanted planes the projections and the tooth comprise respective angular recesses 19 and 20 to establish a fit between each other to ensure blocking of the unscrewing of the lid.
To obtain watertight closure of lid 2 on body 1, the former has on the inside periphery of the bottom, the coupling of gasket 21.
It is understandable that the sealing strap could have one single recess on the periphery. On such case, one of the projections of the skirt of the lid would coincide with the recess, and the other projection would coincide with the tooth of the elastic projection corresponding to the body of the package.
